I already had a double elite drop active before the new event giving double normal scraps was started. Usually, the double elite drop is postponed to the next day (paused basically), so that everyone gets double normal drop and then the double elite drops restart the next day after the event ends. This sucks because I cannot use the double drop that almost every other player is getting

This has been an issue for awhile now. The double drop is in effect and working but as @Sp1tfire said it doesn't display on the campaign map. However, the countdown clock should be present on the event marquee. If it's there it's working.
